IMPROVEMENT IN SIEVES.

Specification forming part of Letters Patent No. 170,117, dated November 16, 1875; application led April 15, 1875.

To all whom it may concern:

Be it known that I, AUeUsTrNE RooT, of Taunton, in the county of Bristol and State of Massachusetts, have invented a new and valuable Improvement in Sitters, ot' which the following, when taken in connection with the accompanying drawing, is a full, clear, and exact specification:

This invention is intended particularly to be used as a coal or ash sitter, but it is also well adapted for sifting sand, emery, and various other articles or substances. I propose to use it for sifting anything to which it maybe adapted.

The coal to be sifted is placed in a rectan gular revolving receiver, which is placed in a dust-tight chamber, and is turned from the outside by means of acrank. The ashes drop into a drawer beneath, and the coal may bel let fall into another drawer by removing the cover from the receiver above mentioned.

The invention in detail is described below.

In the accompanying illustration, Figure l is a front elevation of my sifting apparatus. Fig; 2 is a vertical section of the same. Fig. 3-is a small receiver sometimes used, and Fig. 4 is the large or principal receiver.

Similar letters otret'erence indicate corresponding parts.

a is a box, made of tin or other material, andholdin g the receiver in which the coal is sited. a is the cover, made, as nearly as possible, dust-tight. bis a ange', (of which there are four,) serving to guide the sifte'd ashes directly into the centerof the receptacle prepared for them.

Atthe point c the box a is set into or'upon a box, d, said box cl being provided with feet d. The. two boxes a d may be attached together or not, as desired, or they may both be made in one piece, if considered preferable. 'e is a drawer, sliding upon e, and provided with handle e', into which the sifted ashes drop." f is a drawer, provided with handle f', Vinto which the coal drops after the ashes are sifted out of it. g is a receiver, having wire net-work upon its top, bottom, and sides, andsuspended in the center of the box a by means of the shafts h, one ot' which terminates in a crank, h'. k is the top'or cover of the receiver g. k is the handle. l is the device for locking the cover k upon the receiver g. It swings from the point l', and, by means of its raised end l, presses against the frame of the receiver, and forces the opposite ends of the cover k into the spaces g under the said frame. thus securely fastening the cover in the receiver. m is a ridge, built in the cover 7c, and, with the raised end Z,

cover k removed by means of the handle k.

Enough coal and ashes `to nearly till the re ceiver g are then placed init, and the cover k is then firmly locked in the receiver g. p

To replace the cover la, rst place the righthand end into the space g 5 then push the left end into the opposite space g until the ridge,

m strikes the frame ofthe receiver then force the swinging piece into the position shown in Fig. 4.

By turning the crank h', the contents of the receiver are violently shaken, receiving, as it were, a series of falls, and in less than a minutc are thoroughly sifted, the ashes falling into the drawer e. The drawer e is then removed, the cover 7c taken oft', and the crank h turned untilV the coal in the receiver falls into the lower drawer f. The coal and ashes are now separated and ready for use.

As this sifter is intended to sift other things,

as sand, emery, &c., as well as coal, I have shown a smaller and liner receiver, which may be placed inside the receiver g, it' desired.

This receiver is lettered n, n being the cover, i

and o the lock swinging from the point o. This may be used to make liner ashes, if deemed advisable. Y

It will bevseen that by means of this iuvention the coal can be thoroughly sifted, the coal and ashes dropped into separate receptacles, and no dust raised, in an almost incredibly short space ot' time.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, Ais

The sifting .device above describe-d, consist` ing of the box a a', box d, receiver g lc, receivera n', anges b, and drawers c f, constructed, combined, and arranged substantially as herein described.V AUGUSTINE ROOT.
